I did something really dumb today.

Well today I yanked the motor out of my donor vehicle. 454, says Hi PER Pass on the back of the block...cool.

Here's the dumb thing I did though. The donor vehicle has been sitting all winter, I turned it over a few times and let it run for a few minutes and all seemed good.

Well today I had to move the vehicle to get it in position to rob the jewels. I only had it running for a few minutes but temp gauge went psycho high. Didn't think too much of it, until I bothered to think that there might not be fluid in the radiator...possible leak.

Looking under the motor I seen one of my freeze plugs blew out over the winter....

We got the motor yanked, I drained the oil and didn't see any water or A.F.

vehicle only ran for MAYBE 3-4 minutes...no more. I know, I know...only way to know for sure is to get it magnafuxed. But what are the real odds that I smoked something?

The odds are that running it didn't hurt the motor ( unless you heard some bad noises before shuting it down) but, if it froze solid enough to push out a freeze plug over the winter, I would definately get the block and heads checked before starting a buildup!

Yeah I'm thinking of running it as is for awhile. Get the rest of the rod put together. Then maybe worry about putting more money into upgrades.

You didn't do it any good but if it survived being frozen with out cracking anything it probably be ok.

Yikes, flashack!
I rebuilt a 351 M in a ford truck. Long story short, block froze, popped a plug. Thought I got away with it.. no such luck. It caused a hairline crack in one cylinder that would cause the cooling system to become pressurized.. really pressurized.(enough to spew a column of water about 8 ft. in a continuous stream when the rad cap was taken off) Make sure you have a machine shop check the cylinder bores before you invest a lot of money. It took a while to figure out that one as it seemed like a problem with a head or head gasket.
